抚仙湖有机污染物化学背景值及人淋巴细胞体外致突变性评定

THE BACKGROUND CONTENT OF ORGANIC CHEMICALS AND MUTAGENICITY A SSESSMENT OF HUMAN LYMPHOCYTES IN VITRO OF WATER FROM FUXIAN LAKE

用ＸＡＤ－２树脂提取抚仙湖７个采样点的有机物质水样提取物，用气相色谱／质谱（ＧＣ／ＭＳ）进行分析。在每种水样品中发现有上百种有机污染物。提取物用培养的人淋巴细胞系姐妹染色单体交换（ＳＣＥ）试验作致突变潜力检查。结果显示，仅入湖口水样在高浓度组（００６２５Ｌ／ｍＬ）⑥诱发ＳＣＥ明显增加。

The organic substance in test sample were extracted by XAD-2,and the extracts o f water sample in seven localities from lake water sample of Fuxian Lake were an alyzed by gas chromatography mass spectrometry (GC/MS).Over hundred organic pol lutants were discovered in every water sample.The extracts were examined for mut agenic potential by the sister chromatid exchanges (SCEs) test in cultured huma n lymphocyte.According to our results,the water sample of Ruhukou only at highe r concentration group (0 0625 L/mL) induced a significant increase for SCE.
